31
Q

Patho of increased ICP

A

Cerebral bl flow decreases, which results in ischemia and cell death. A sympathetic response is activated which causes a subsequent increase in BP. The increased BP then activates the parasympathetic system via carotid artery baroreceptors resulting in a vagal induced bradycardia. (Cushings reflex)
